l To alZZ whom it may concern.-

Beit known that I, WALTER H. BARTHOLO- MEW, of East Orange, county of Essex, and State of New Jersey, have invented certain new and useful Im rovements in Distilling Apparatus, of whic the following is a full, clear, and exact speciiication, reference being had to the accompany-ing drawings, wheein- Figine 1 is an elevation partly-sectional view of a water-distilliuff apparatus embodying my invention, and Fig. 2 an'elevation partly-sectional view-of a modified construction of the receptacle for the still.

My invention, set forth in this application and in my application filed May 8, 1905, Se` rial No. 259,362, relates to distilling apparatuses, more particularly such as are used for distilling water in large quantities; and the invention set forth and claimed herein consists more particularly of the hereinafterdescribed improvements in the construction of such distilling apparatus and in the combination of its parts as set forth in the claims.

I have found by experiments and observation of the process of distilling that a large proportion of the substances suspended in' the Water, including those held in solution, are precipitated, While others rise to the surface, when the temperature of the water is changed. This discovery is utilized in my improved apparatus 'by devising means for such changing the temperature of the water to be distilled and for removing Jfrom it such substances before it is fed into the `still, and thus largely eliminating impurities from the water to be distilled before it is fed into the still or evaporator, These devices are so combined in my improved a paratus with the other essential parts of suc i an apparatus that the operations are carried Qn continuousl and successively.

T e apparatus embodying my invention com rises a steam-boiler A, an evaporator or still a feed-water receptacle 6 for the still, one or more condensers C, the conduits, and the auxiliary devices used in combination therewith, as more fully ex lained farther on. The steam-boiler A may e of any suitable type, its ob'ect being 'to generate steam, which is con ucted by pipe 1 into the still B,

' i "where it passes through the coil i2 and leaves the still again'through pipe 3, 4returning to the boiler. The still B is a closed vessel of any suitable type, wherein a steam-coil 2 is located and connected with the conduits l1 and 3, as explained above. The dome ofthe still B connects with the vapor-conduit 4, throu h which the va ors pass from the still into t e condenser. he condenser C used in 'my improved dstilling apparatus' forms the subject-matter of my ap lication Serial No. 259,361, as referred to a ove, and comprises a comparatively long (high) cylindrical vessel 11 with a suitably-cular ed ared base 12 and With the concentrica lysuperimposed acket 9, water-tightly secured I. tothe hull of t e interior vessel 11 at 14. An

inlet-pipe 15 is tapped into the jacket some distance above t e bottom thereof and is connected to a ump or'other source of supply of water. the bottom 13 of the jacket a discharge-pi e 16, provided with a stopco'ck, is set. T ls pipe 16 is used lfor discharge of sediments and precipitated substances contained in the water. jacket 9 is open, and pipe 8 connectswith it at The upper end of or belowthe level of its upper rim, conveying y the partly-heated and partly-purified water into the rece tacle 6, from where it is fed into the still. T e construction of this receptacle 6 and its connections with the feed-pipe 5 and the pipey 8- are devised with the same object in view to facilitate a further partial purification of the Water to be distilled. Pipev 8-v extends some distance into the receptac and the latter is provided with an overflow. The consumption of Water fed into the still is considerably less than the supply flowing into receptacle 6 through pipe 8, and thus whatever .impurities may be in the Water floating on its surface by reason of the heating of the water in jacket 9 or otherwise are carried ofi' by the overflow.

Feed-pipe 5, which feeds the water from the receptacle 6 to the still, is shown in Fi 1 tapped into the side of receptacle 6 at a istance from the-bottom ofthe receptacle. As shown in Fig. 2, the pipe 5 projects upwardly through the bottom ofrece tacle 6 to a distance above the bottom o the receptacle. Thereby a receptacle is created between the aperture of pipe 5 and the bottom lof the stand-pipe 6 for the accumulation of sediments and precipitated substances. -There IOO thc sed' wenn is 1 up Li on of Ai u 19in mm at Smm ndmg 1h mi( @mimo Siefmmwt TQ. bedlschal '"id, inta?,
